Application of Nanotechnology in Water Treatment and Wastewater Recovery

Abstract

"Ensuring clean drinking water" is a major challenge facing mankind in this century.The world's population base is large, the total population is growing, the water pollution is becoming more and more serious, and it is more and more difficult to remove. At the same time, due to climate change, many places have appeared the phenomenon of "shortage of fresh water resources", so the recycling and reuse of sewage to turn it into drinking water has become an urgent problem in contemporary society.However, the existing sewage treatment technology can not achieve the expected water purification effect. The emergence of nanotechnology provides an opportunity to develop a new generation of sewage treatment technology, indicating the direction of research and development of a new generation of water purifier.
